A tie rod cylinder is a type of pneumatic or hydraulic actuator where the front cap, barrel, and rear cap are securely fastened together using threaded tie rods. One of its distinguishing features is its round barrel construction, which is common across most tie rod cylinder designs.

These cylinders are widely used in industrial machinery and dust collection systems, and they are well-suited for customization. Depending on customer requirements, various bore sizes can be produced—including large-bore cylinders with diameters up to 500 mm.

 What’s The Single-Acting Tie Rod Cylinder

While most tie rod cylinders are double-acting, single-acting models are also available for specific applications. In a single-acting design, compressed air (or hydraulic fluid) is applied to only one side of the piston, with a spring or external force used to return it to its original position.

 Key Features:

Simplified control system — requires only a 3/2-way solenoid valve

Spring return or spring extend configuration depending on use case

Lower air consumption compared to double-acting models

Ideal for applications where the return stroke does not require force

Compact and cost-effective in systems with limited space or control complexity

 What’s the Double-Acting Cylinder

Nearly all tie rod cylinders are double-acting, meaning they use air or hydraulic pressure for both the extension and retraction strokes. Most models come with:

1. Adjustable cushioning to absorb impact at end-of-stroke
2. Optional high-temperature seals
3. Multiple mounting options.

A special bi-directional sealing structure ensures both tight sealing and oil storage functionality. These cylinders are typically controlled by a 5/2-way solenoid valve.
